Automatic start-up with valves

Turn the corresponding knob anticlockwise up

to the maximum position (large flame, fig. 1) and

press the knob.

Once the burner has been started up, keep the

knob pressed for about 6 seconds.

ATTENTION: the triple ring burner switches on

only in the maximum flame position

Using the burners

In order to obtain the maximum yield without

waste of gas, it is important that the diameter of

the pot is suitable for the burner potential (see the

following table), so as to avoid that the flame going

out (fig. 2).

Use the maximum capacity to quickly make

liquids reach boiling temperature, and the reduced

capacity to heat food or maintain boiling. All of the

operating positions must be chosen between the

maximum and the minimum ones, never between

the minimum position and the closing point.

The gas supply can be interrupted by turning

the knob clockwise up to the closing position. If

there is no power supply, it is possible to light the

burners with matches, setting the knob to the start-

up point (large flame, fig. 1).

It is important to use cookware with the sizes

specified and ensure the cookware is always

correctly centred over the burner. Using

oversize cookware can potentially cause heat

damage to your benchtop and/or control knobs

which will not be covered under warranty.

Notice

– When the equipment is not working, always

check that the knobs are in the closing position

(see fig.1).

– If the flame should blow out accidentally, the

safety valve will automatically stop the gas

supply, after a few seconds. To restore operation,

set the knob to the lighting point (large flame, fig.

1) and press.

– While cooking with fat or oil, pay the utmost

attention as these substances can catch fire

when overheated.

– Do not place unstable or deformed pots on the

burner, so as to prevent them from overturning or

overflowing.

– Handles should be turned away from the front of

the bench to avoid accidents.

– When the burner is started up, check that the

flame is regular and, before taking pots away,

always lower the flame or put it out.

INSTRUCTIONS FOR THE INSTALLER

OPERATION ON N.G / S.N.G.

Gas Connection

This appliance is supplied for use with Natural

Gas. However, it can be converted for use with

LPG. Refer to LP conversion chapter.

Supply pipe sizing

The total hourly gas consumption for the appliance

is shown on the data label. The required supply

pressure (i.e. at inlet to appliance regulator) for

each gas type is shown on the data label, and

given in page "TECHNICAL CHARACTERISTIC

TABLES". Use this information in conjunction with

the length of run, number of elbows, tees and

bends, the available service pressure and the

supply requirements of other installed appliances

to determine a suitable pipe size. For assistance in

this matter refer to the appropriate section of the

Installation Code AS5601.

An AGA certified class B or D flexible connection

may be used to connect the cooktop in accordance

with the AS5601 and in particular section 4.8.

Where a hose assembly is used and the cooktop

is in the installed position, the hose assembly shall

be suitable for connection to a fixed consumer

piping outlet located at a point 800 - 850mm above

the floor and in the region outside the width of the

appliance to a distance of 250mm. The point of

connection to consumer piping must be accessible

with appliance installed.

Elbow positioning

It is possible to reposition the elbow if required by

loosening the locking nut and elbow by using two

spanners. Re-tighten the entire assembly after the

elbow has been repositioned. When fitting elbow to

appliance, ensure that the sealing washer is fitted.

Regulator

An appliance regulator is provided. The regulator

must be positioned so that the pressure test nipple is

accessible when the appliance is installed. Connect

the gas supply to the ½” tapered internal thread inlet

of the regulator. Refer page 11 for connection point

position.

Assembly of Regulator

The assembly of the regulator to the cooktop

manifold is achieved via the elbow union and

sealing washer supplied.

The ½” parallel thread connects to the manifold, and

the sealing washer is placed between the manifold

end and the flat face on the elbow.

The ½” tapered thread connects to the outlet of

the regulator, and is sealed on the thread using

approved thread sealing tape or approved thread

sealing compound.

The inlet of the regulator is a ½” tapered internal

thread and is connected to consumer piping or hose

assembly.

Regulators are supplied pre-adjusted and

configured by the component maker for use with

Natural Gas.

The appliance installer is not required to make an

adjustment to obtain the correct outlet pressure

setting.

An arrow on the base of the regulator indicates the

direction of gas flow when the inlet and outlet of the

regulator is orientated correctly. When the regulator

has been fitted, check for leaks from the connections

with soapy water.

Checking the gas supply

Check the manometer zero point is correct.

Connect the manometer to the cooktop

pressure point. This is located on the

regulator.

Turn on the gas supply and electricity and try

to ignite the gas. NOTE! lt will take additional

time to light the gas for the first time as air

needs to be purged from the pipes.

With the appliance operating check the outlet

pressure

• when all burners of the appliance are

operating at maximum,

• When the smallest burner of the appliance is

operating at minimum.

Under these conditions the outlet pressure should

not vary from the nominal outlet pressure of

1.00kPa by more than ± 0.20kPa

If the regulator appears to not perform

satisfactorily, then check the following points:

If the outlet pressure is consistently too low

then the inlet pressure may be too low and

adjustment of an upstream regulator may be

needed, or an upstream regulator or valve

with insufficient flow capacity may be present

in the gas supply line. If this is suspected then

it may be necessary to repeat the checks

whilst measuring both the inlet and outlet

pressure to determine if the inlet pressure is

in the range 1.13 - 5kPa.

Check that the regulator has been fitted to the

gas supply line in the correct orientation, the

arrow on the base of the body indicates the

direction of gas flow.

Once these checks have been completed, if the

regulator still fails to perform in a satisfactory

manner, it should be replaced.

INSTRUCTIONS FOR THE INS

ALLER

Electrical connection

The appliance is supplied with a standard 10

Amp service cord terminated by a 3-pin plug for

connection to a standard household socket. The

electrical supply is required to power the electronic

ignition system.

NOTE: It will be necessary for servicing purposes

to disconnect the electrical power supply. The

power point should therefore be accessible after

the appliance is installed, as specified in the local

wiring regulations.

TESTING APPLIANCE OPERATION

After installation the installer must fully test the

appliance and ensure it operates correctly before

handing it over to the customer.

LPG ensure that the NG regulator is removed

and replaced with the Test Point Assembly. An

AGA Approved gas regulator suitable for a supply

pressure of 2.75kPa should be part of the gas

tank supply and the test point pressure should be

adjusted to 2.75kPa.

Replacing the injectors

If the equipment is adjusted for a type of gas that is

different from the one available, it is necessary to

replace the burner injectors.

The choice of the injectors to replace must be

made according to the table of the “technical

characteristics” as enclosed.

Act as follows:

– Remove the racks and burners.

– By means of a straight spanner L, unscrew

the injectors U (fig. 7) and substitute it with the

corresponding one.

– Tighten the injectors strongly.

After changing the injectors, it is necessary to

eliminate residual natural gas in the system.

To do this you have to turn to the maximum

position then press the knob of each burner and

wait few seconds.

Adjusting the burners

The lowest flame point must always be properly

adjusted and the flame must remain on even if

there is an abrupt shift from the maximum to the

minimum position.

If this is not so, it is necessary to adjust the lowest

flame point as follows:

– start the burner up

– turn the tap up to the minimum position (small

flame)

– remove the knob from the tap rod

– Introduce a flat-tip screwdriver in the hole F of the

tap (fig.8-8/A) and turn the by-pass screw up to

a proper adjustment of the lowest flame point.

As regards U-LPG gas burners, the by-pass

screw must be tightened completely.
